HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 784,372, dated March'7, 1905.

Applica-tion filed September 8 1904. Serial No. 223.678.

To @ZZ who/1t t ift/Ly concern.'

Be it known that I, 1V ILLIAM H. ALBEE, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented a new and ImprovedHose-Coupling, of which the following' is a full, clear, and exactdescription.

My invention relates to hose-couplings, and has for its principalobjects the provision of a secure and readily-operated device which willbe effective to lock both the exterior' and interior of the hose againstdisengagement.

It consists in the various features and combinations hereinafterdescribed and more particularly claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure l is a side elevation of one embodiment of my invention. Fig. 2is a central vertical longitudinal section therethrough.. Fig. 3 is aside elevation of one of the coupling' members. Fig. 4 shows thecompressible sleeve in side elevation. Fig. 5 is an end elevation ofsaid sleeve, and Fig. 6 is a transverse section on the line 6 6 of Fig'.3.

1() designates a coupling member having at one end an annular flange 11,which eoacts with a fiang'e 12 upon acoupling-nut 13. This nut engages athread at 14 upon a second coupling member 15, it extending to a fiange16 encircling' the same, this nut serving to draw the coupling' memberstogether in the usual manner, there preferably being interposed betweentheir ends a suitable washer 1V. Beyond the flange is shown a depressionV17, which is preferably continuous and annular and which receives aprojection in the form of an annular flang'e 18, extending inwardly fromthe extremity of a sleeve 19, which is separated from the couplingmember 15 sufiicientl y to furnish a space to receive the hose H. Thissleeve is divided longitudinally at 20, thus enabling its flange to besprung into the depression, and is compressible, it being provided atits ends with slots 2.0,extending from points near the center inopposite directions and alternating with one another. The sleeve isthreaded upon its exterior to receive nuts or collars 2l, having' theirinner engaging' faces inclined or converging' outwardly. Both thecoupling members vhave hose-receiving depressions 22 of trapezoidalform, their inclined sides converging toward the outer ends of themembers. There may be further provided separated depressions' 23,conveniently circular in form, opening from the bottoms of' thedepressions 2Q, there being' three of the former for each of the latter.g

1n use the end of the hose is introduced between the coupling member andthe divided sleeve and the. nuts 21 turned toward one another. Thiscompresses the ends of the sleeve, forcing the hose into both thetrapezoidal and circular recesses. As a result said hose will be lockedupon the coupling' member by the engagement of its inner and outerfaces, the former extending into the depressions and, by virtue of theconvergence of the sides, resisting longitudinal displacement morefirmly the greater the pull upon it, this thrusting' together of theportion of the hose within the larger depression also tending' to pressthe material in the circulaidepressions farther into them. As will beseen in Fig. 2 of the drawings, the outer surface of the hose within thesleeve assumes a ridged or V shape, which prevents its separation fromthe sleeve, and as this sleeve is in coaction, through its flange, withthe coupling member the effect is to lock the outer surface to saidmember. Thus a double resistance is offered to separation. It will alsobe seen that on account of the longitudinal division or slot 20extending' throughout the length of' the sleeve and thol slots 20"extending less than half-way in from vthe opposite ends the sleeve willbe enabled to contract more at the ends than at the center. This willgive the arched shape shown in Fig. 2 and provides a very efficient holdfor the hose.
